34 Cruise Report, RV ATAIR, Cruise 067I033-1, Bremerhaven – Thybor?n – Aberdeen, 23 Jul – 15 Aug 2024 the deep northern North Sea to the shallow southern North Sea, the lower part of the water column is typically colder in the north. The water column is typically more homogeneous in the south and becomes increasingly stratified in temperature towards the north. The input of At- lantic Water across the northern boundaries of the North Sea and its subsequent propagation within the North Sea is obvious through salinities exceeding 35 and in summer 2024 reaches as far south as 58°N. Figure 6.7. Potential temperature [°C] (left) and salinity (right) along 59°N, 58°N and 57°N (from top to bottom) as observed during cruise 067I033-1, summer 2024. Superimposed white contours highlight selected ??-isopycnals. CTD measurements along 60°N were not possible due to unfavourable weather conditions. For the same reason, data along 59°N exists only for its western part.
